The theft was discovered yesterday when Khloe, 29, and her mother Kris Jenner went to the house to clean it for its new owner, reported TMZ.

According to the sources at the law enforcement office the theft was an inside job because there were no signs of forced entry. "Thieves... Someone's about to have some bad Karma coming their way," Khloe posted on Twitter.

The 'Keeping Up with the Kardashians' star reportedly wants people who had access to the house, such as house staff, assistants, filming crews, inspectors and movers, to take lie detector tests. Khloe filed for divorce from Lamar in December after 4 years of marriage.
